Use the symbolic form of the gas cost of fill-up function,, to evaluate

UkoKoshka [18]

Answer:

0, $12.40, $24.79, $37.19, $49.58

0 ≤ f(g) ≤ 49.58

Step-by-step explanation:

The cost of fill up gas, f(g) as a function of number of gallons of gas needed (g) is given by f(g) = 2.479g ........(1)

So, f(0) = $0

f(5) = 2.479 × 5 = $12.40

f(10) = 2.479 × 10 = $24.79

f(15) = 2.479 × 15 = $37.19

and f(20) = 2.479 × 20 = $49.58

And the practical range of this function is 0 ≤ f(g) ≤ 49.58

Therefore, option D is correct. (Answer)

Point G is rotated 90°. The coordinate of the pre-image point G was (7.5), and its image Gʻis at the coordinate (5, 7).

matrenka [14]

<h3>Answer:</h3><h3>The Direction of the rotation is counterclockwise around the origin.</h3>

Step-by-step explanation:

What was Given was that Point G is rotated 90°. The coordinate of the pre-image point G was (7, –5), and its image G’ is at the coordinate (5, 7).

What you need to find was : What is the direction of the rotation.

So coming to conclusions is we have given that Point G is rotated 90°.

The Pre-image of G = ( 7, -5).

Translated image G' = ( 5 ,7).

By the Rotation rule of 90° is : (-y, x) 90 degree rotation counterclockwise around the origin.

(y, -x) 90 degree rotation clockwise about the origin.

We can from G (7,-5) and G'( 5 ,7) it is rotation counterclockwise around the origin.

Therefore, Direction of rotation is counterclockwise around the origin.

-4(6x+3)= -12(x+ 10)

Lilit [14]

Answer:

Step-by-step explanation:

-4(6x+3)= -12(x+10)

<u><em>Let's do the first part:</em></u>

-4(6x+3)

<em>**distribute**</em>

-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12

<u><em>Let's do the second part:</em></u>

-12(x+10)

<em>**distribute**</em>

-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120

-24x -12 = -12x - 120

<em>**Move variable to the left-hand side and change its sign**</em>

-24x +12x -12 = -120

-12x - 12 = -120

-12x = 108

x = 108/-12

x=9

Write an equation in slope-intercept form that contains the points (2, 8) and (4, 9).

ololo11 [35]

Given two points, the equation of the line in slope form can be obtained using this equation

$\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{y_{}-y_1}{x_{}-x_1}$

Now we can name the points

x1 = 2, y1 = 8

x2 = 4 , y2 =9

These coordinates can then be substituted into the equation

$\frac{9-8}{4-2}\text{ =}\frac{y\text{ - 8}}{x\text{ - 2}}$

$\begin{gathered} \frac{1}{2}\text{ = }\frac{y\text{ - 8}}{x\text{ - 2}} \\ \\ x-2\text{ = 2 (y - 8)} \\ \\ x\text{ - 2 = 2y - 16} \end{gathered}$

x - 2 + 16 = 2y

2y = x - 2 +16

2y = x + 14

Divide both sides by 2

y = x/2 + 14/2

$y\text{ = }\frac{x}{2}\text{ + 7}$

This is the equation in slope-intercept form

where the slope = 1/2
